Rectangle area = length(l)x width(w)

9/2 = 4.5

4.5(l) x 10(w) = 45ft

Deffense [45]

Answer:

The percentage decrease of the number of visitors to Alec's website from February to March is 14.8 %

Step-by-step explanation:

Explanation:

Percent decrease is a measure of percent change, which is the extent to which something loses value.

Step 1:

Find out the difference (decrease) between the number of visitors in march and February

Decrease =number of visitors in Fe bury- Number of vsitors in march

Decrease= 1,586- 1,352

Decrease =234

Step 2:

Divide the decrease by the original number of visitors and multiply the answer by 100.

Percent decrease= $\frac{Decrease }{ Original Number }\times100$

Percent decrease= $\frac{236}{1586}\times100$

Percent decrease= $0.148\times100$

Percent decrease =14.88

nalin [4]

Answer:

option A: 120°

Step-by-step explanation:

$Area \ of \ circle = \pi r^2\\\\Area \ of \ sector = \pi r^2 \frac{ \theta}{360}\\\\Ratio \ of \ sector \ to \ circle = \frac{1}{3}\\\\That is, \\\frac{1}{3} = \frac{\pi r^2 \frac{\theta}{360}} {\pi r^2}\\\\\\\frac{1}{3} = \frac{\theta}{360} \\\\\frac{360}{3} = \theta\\\\120 = \theta$
